MULTI-STAGE TERMINAL OUTPUTS

Refer to equipment manufacturers’ instruc- tions for specific system wiring information.

You can configure the thermostat for use with either multi-stage electric heat systems or multi-stage gas systems. When configured

for electric heat, the G terminal (blower/fan) will be energized on a call for heat, using the installer table (pgs. 5 & 6).

This thermostat is designed to operate a single-transformer system. If you have a two- transformer system, cut and tape off one transformer. If transformer safety circuits are in only one of the systems, remove the transformer of the system with NO safety circuits. If required, replace remaining transformer with a 75VA Class II transformer. After disconnecting one transformer, the two commons must be jumpered together.

Use the terminal output information below to help you wire the thermostat properly for your multi-stage system. After wiring, see

CONFIGURATIONsection for proper thermostat configuration.

HEAT PUMP TERMINAL OUTPUTS

Refer to equipment manufacturers’ instruc- tions for specific system wiring information.

You can configure the thermostat for use with the following heat pump system types:

HEAT PUMP TYPE

1.

Single-stage

compressor

system;

gas or electric backup.

HEAT PUMP TYPE

2.

Multi-stage or two-

compressor

system;

gas or electric backup.

This thermostat is designed to operate a single-transformer system. If you have a two- transformer system, cut and tape off one transformer. If transformer safety circuits are in only one of the systems, remove the transformer of the system with NO safety circuits. If required, replace remaining transformer with a 75VA Class II transformer. After disconnecting one transformer, the two commons must be jumpered together.
